Hi guys,

2 days ago I passed from kang cm7 to

miui 2.4.13 without workaround and I had not the r/w issue,

I just flashed the rom, the traslation pack then the 3.0.y kernel...

all is ok
[LG Optimus 2x] extreme79:
Check this

android.media.MediaPlayer (cloudtv.cloudskipper.Cloudskipper): 22 m 43 s (1363 s) Count:14 2.3%

Try to uninstall this and check if somethign change
[LG Optimus 2x] mrgian:
With the latest kernel, my phone drains 6% for 2 hours without being used. Everyone? Were you experiencing this? Im using the non ds version, no oc/uc.
[LG Optimus 2x] eyronic:
I'm not. I'm using the DS w/ OC btw.
[LG Optimus 2x] mrgian:
the ds version gives false battery percentage in my experience thats why i use the non ds version.
[LG Optimus 2x] upetro:
I am using the Non DS with oc(1200mhz in my case) and i get great battery life! The best so far. Thanks Vadonka, you are the best!
[LG Optimus 2x] Ancalagon_ZA:
Does anyone get BSODs while charging using this kernel? Thinking of switching to it.
[LG Optimus 2x] alakyr:
vadonka before i had the break launch with the nvidia italia pr (the one behind the italian official page) and he was speechless for how much my o2x is fast and smooth and this thank to your kernel and temasek's kang! Unlucky he don't have no more the dual but the htc one x with tegra3
[LG Optimus 2x] Shadowchaz:
I do but it's a small problem. Kernal runs great.
[LG Optimus 2x] Ancalagon_ZA:
How often? Less often than stock CM7 kernel?
[LG Optimus 2x] @dap:
BSOD not a problem relative to stock CM7, I don't think, and this kernel is fast and smooth. It's also well-supported by Vadonka and others. :)
[LG Optimus 2x] vadonka:
i run out of 'thanks' guys :p
[LG Optimus 2x] @dap:
Hah, you should have lots of them! Your thanks meter is only slightly less than your number of posts! ;)
[LG Optimus 2x] vadonka:
heh, you right. i dont even see this :)
[LG Optimus 2x] hadi_rena:
Don't this is normal because I listening to music this day ? Anyway I uninstalled it to check... If that the culprit then bye bye cloudskipper :D
[LG Optimus 2x] Shadowchaz:
I don't know I've never used the stock kernal.

Best thing to do is try it. Our phones tend to have slight variations in tolerances. For example I can overclock alot but i get charging bsod. Other people can't overclock but don't suffer bsod. Just backup then try it... if you have a problem then just roll back your installation :)
[LG Optimus 2x] yukkio:
Back to v2 because i've the system r/w problem with v3, again. No solution works for me.

BR.
[LG Optimus 2x] penzo10:
Hey guys!

First of all...thanks for all the hard work and dedication that you are putting into this.

I have a small problem...I am on Teamsek CM/7 kang 91 and when I flashed your kernel I got - no signal.

In getril baseband is unknown. What can I do to make it work? Should I reflash baseband? If so, which one should I choose?

I should make nandroid backup first, not to loose all my programs and settings?

thanks a lot
[LG Optimus 2x] Lapiduss:
Try to reinstall Temasek 91 and after the kernel
[LG Optimus 2x] extreme79:
Probably you installed with your baseband an incompatible Ril using GetRil.

Try to restore the getril's autobackup.
[LG Optimus 2x] alakyr:
CM support only froyo RIL....you u install a GB ril i got this problem
[LG Optimus 2x] mrgian:
i didnt have this problem. but, try to reflash rom. maybe theres just an error along the way. hope it works!
[LG Optimus 2x] TrymHansen:
A heads up that I've made an app to control cpu-related parameters on OTF-compatible kernels. Uses the tweakaio-system on etana-kernels.

App is here.
[LG Optimus 2x] tomislav177:
Hello my friends. With my phone everything was ok but it was too hot. :)

I have enabeld lover voltages and so far for two all days, my mobile phone is ok. It was stressed with Quadrant and system stability test 2.4

What I want to tell you is that my phone is now much cooler then before and obviously battery lasts longer.

I want to ask your opinion can I go lover on other frequencies or not, or can you tell me yours voltages and frequencies. On this pictures are mine frequencies.

P. S.

BE AWARE if you want to undervolt i recommend to set with pimp my cpu without set on boot.
[LG Optimus 2x] bullbutch:
I had the r/w issues on all the latest kernels. I installed supersu instead of superuser. Now all my R/W issues are gone on all kernels.
[LG Optimus 2x] _Vegas:
The "Snappy" sounds good , it's already be included in the ETaNa?
[LG Optimus 2x] Sörnäinen:
Hello altogether,

now this is a noob question, but ... for use with Miui, can I choose the 3.0 kernel, or do I rather stick to the other one? :O
[LG Optimus 2x] pidocchio:
you can use both versions.

the 2.y (official lge kernel plus many cherry picks and customizations) is discontinued and therefore is the most stable, instead 3.y (unofficial, forward ported tegra nvrm/nvodm kernel based on tegra-2.6.32) is in development stage and may contain some bugs and/or lack of features.
[LG Optimus 2x] Nova163:
For me the old kernel is faster, more stable and has better battery life
[LG Optimus 2x] tonyp:
Edit: Yes it is.
[LG Optimus 2x] kickokim:
I think it is, this is a post about a the update ofa few versions ago!

I think you just have to activate compcache in etana app.

Does this kernel install voodoo sound?
[LG Optimus 2x] tonyp:
Whoops, you're totally right. I'm not using ETaNa myself currently but reading the thread, somehow I missed that change - and when I checked in the OP for my post I only read the newest changelog and not the one _right under_ that :D
[LG Optimus 2x] Sörnäinen:
So I will give the old one a shot. Thanks!
[LG Optimus 2x] vadonka:
snappy compression with zram is already in etana. im the first who ported this to the o2x kernels anyway :)

about the speed and the battery life:

kernel 3.0.y faster than 2.6.32.y but its eat more battery a bit for now, but im workin on it
[LG Optimus 2x] _Vegas:
Thx for hard working! Good luck:D
[LG Optimus 2x] Aksuli83:
I have no clue on what information I should post in here so I'll just post what ever I manage to think to.

Heres some background: Bought the device just few days ago, desided to root it in few hours after that and needed a lot of help (since cyanogenmod guide didnt work for me at all) and after about 2 hours it was finally rooted and ROM installed, went for the latest CM stable 7.1.0

Before I had HCT Desire Z and OC it was so easy, so I wanted to OC this too. Noticed that CM dosnt support it directly and that I should change kernel to do so. Since that these few days I been trying different kernels and none of those have worked for me. Phone boots but stays in the empty screen for minutes and minutes and nothing happens. Every time I've tried another kernel I have cleared cache and dalvik as the guides tell me to. So after these 2 days I've desided to ask for help and hoping there is someone that knows wich kernel to put into my phone.

Before rooting doing 'cat /system/build.prop' gave me this => http://pastebin.com/yWgikcDT

After many tries and help from one CM person, he suggested me to try this guide to get my phone rooted : http://xdaforums.com/showthread.php?t=1327599 and it did work and then I could install CM into my phone, finally.

Since that I have tried kernels from SwiftExtreme, vorkKernel, ETaNa LOC/HOC.. And booting dosnt work (waited for roughly 5min to CM loading animation come).

Now doing 'cat /system/build.prop' gives me => http://pastebin.com/tkJ3G1mw

Phone info:

Model number

Optimus 2X

Android Version

2.3.7

Baseband version

1035.21_20110405

Kernel version

2.6.32.45-cyanogenmod

rmcc@giskard #1

CPU info

ARMv7 Processor rev 0 (v7l)

Mod version

CyanogenMod-7.1.0-Optimus2X

Build number

GWK74

Now theres pretty much all I can imagine on giving information. Hope someone knows wich kernel I should apply in order to be able OC my device.
[LG Optimus 2x] Shadowchaz:
Alot of the new kernals only work with the latest nightly builds. Go to temasek thread and download build 91. Then install custom kernel.

Hope that helps :)

[LG Optimus 2x] snel76:
Yes CM7.1 stable is very old, i recomend Temaseks Kang too, after flashing this new kernel should work. I run ETaNa, without problems.
[LG Optimus 2x] Aksuli83:
Thnx guys for the quick reply =) I actually PM'd but then thought I should ask here for if someone other has this problem, he might find the answer here.

How to install over CM7, I tried look at the post in link but theres no guide. Do I need to wipe data, cache and dalvic? Or can I just install the zip and it will overwrite and I dont loose any settings? And if I have to wipe data, there probably isnt a fast easy way to backup my settings and programs and widgets+locations of them to the kang...

Thnx in advance =)

EDIT: I actually went and tried to install it over the old CM7. Wiped cache and dalvic and then installed update. And it all worked =) So thats it. Thanx guys for your help =)
[LG Optimus 2x] tonyp:
Thanks a lot for this idea and your hard work vadonka!!

It is a great commit, scrolling is more fluid and apps like facebook start faster.

You're putting so much effort into our phone, we can't thank you enough.
[LG Optimus 2x] temasek:
Oh I've no idea vadonka u are the 1st to port snappy over to p990.

Nice work!
[LG Optimus 2x] powwow88:
Wipe cache and dalvik should be enough. Btw. rooting stock GB is easy with latest SuperOneClick.

About the latest 3.0.y kernel: I used setcpu profiles i deleted and it seems now only wifi drains too much battery.
[LG Optimus 2x] extreme79:
How can I check what battery driver is installed? Because I tried the DS version some weeks ago, actually I use an oc 'standard' but sometimes I get funky battery readings.. And it's a bit strange.
[LG Optimus 2x] temasek:
Not just that.

Vadonka is the host for cm7 & cm9 unofficial builds.

Thanks vadonka!
[LG Optimus 2x] Aksuli83:
I just did as you guys told me to. Got it workin! Thanx a lot mates. Now I'm only wondering the OC and UV settings and temperature but I guess I'll get them figured out.

Hope someone else sees it helpfull and heres a quick summary:

If you got CM7 installed to your phone and tried to instal OC kernel, and failed:

Goto temasek thread and download atleast build 91 temasek's RC-1 build 91

Then download the custom kernel (example ETaNa )

Move to SD card, boot to recovery and make backup.

Clear cache and dalvik. Install temasek update from zip and then install kernel (I booted my phone between this) and ur done.

And thnx for the great guys makin this possible. => temasek and Vadonka <=
[LG Optimus 2x] :
Vadonka, thanks for all the great work!

Do I have to enable snappy, or is it used by default?
[LG Optimus 2x] @dap:
3.0.y is awesome, man, and soooo smooooth!:D

Really appreciate all your work -thank you.
[LG Optimus 2x] kickokim:
Also, don't use external app for oc yet because you will have cpu1 always on (and bad battery drain). Use the cm7 performance/cpu settings and etana app for uv and other settings.
[LG Optimus 2x] antec123:
i have strange issue, after charging then wait for about 15 minutes my phone shut off it self. i use cm7 kang 91 and latest kernel 1804. does anyone happen on your phone too??? before i use cm7 kang 83 and latest kernel 1804 it's okay, phone never shut off by it self...

i think i have to go back to kang 83 again :(

i use pimp my cpu v5.0 and already set the minimum value to 324 instead 216 mhz but strange it shut off it self....

OTF settings:

powersave mode= 0

nitro enable = off
[LG Optimus 2x] k101d:
Work fine with WiUi 2.4.20 except..

Flash version April 18 (1204181216) with WiUi 2.4.20 my phone has decrease in sound level I set all to maximum level it seem to be equivalent with previous not flash at 70-80% level.

And I unmark option of update su in etana.conf before flash then after flash /system can't set to R/W I had solved this by install superuser download from play store.:cool:
[LG Optimus 2x] Aksuli83:
Think i need to try this without CPU master then.. battery drain is almost horrible tho already. Im using the same settings as in HTC Desire Z and it did easily a full day at my usage and this LG just dosnt even get close.. Well anyways gotta try without the ext-apt for oc...
[LG Optimus 2x] vadonka:
Kernel is updated, and provide better battery life i hope :)

at least after 24 hour i still have 64% with phone calls, email, mp3

ps.: snappy compression mean, that the zram driver use the snappy compressor instead of the lzo compressor for the memory compression, its no need to activate with special way, only need to enable the compcache. it just a part of the zram driver.

lzo compression provide a little bit smaller data size, so the snappy compressor is not so "effective", but the snappy is almost twice as fast like the lzo... and this is more important :)

Hi Vadonka, after flashing kernel 23 Apr my phone shut down immediately after entering second LG logo. Do you have any idea that causing this?

I'm using WIUI 2.4.20, at the moment flash back to kernel 18 Apr.

read the op post.
[LG Optimus 2x] reginickneo:
No oc booted. Maybe I should wait more at oc ver. (Only waited for 5 min)
[LG Optimus 2x] alakyr:
then you suggest to enable compcache to use this faster solution right? and then which setting you suggest on the kang? 10%, 18%(default) or 26%?

EDIT: if i remove the etana tweakaio program is safe or some features of the kernel stop working?
[LG Optimus 2x] powwow88:
i flashed today's 3.0.y oc, otf, default battery driver and my phone freezes at 2nd LG logo. I'm using Temasek kang 89.

[LG Optimus 2x] alakyr:
just updated and my o2x work smoother and faster then the 18april version...before install it you have wiped cache and dalvik?
[LG Optimus 2x] elganso:
I'm using 3.0.29 kernel with the latest WIUI firmware and 0725 (V10d Europe) baseband.

I've read that combination should give me good battery data, but I can't reach more that 10-11h of battry lifetime.

I've always tried the non-overclocked version (both stock and DS versions). Should overclock give me better or worse battery lifetimes?

Also, I've tried using the undervolt option in the TweakAIO app (with the default parameters). Is that correct? Which app can I use any other app to over/underclock? Can you give me your exact configuration?

Sorry if I'm asking something everyone should know, but I'm done my best searching with no results :rolleyes:

Thanks!
[LG Optimus 2x] antec123:
isn't that in default on tweakio.conf. it already set right??

Can I update from 120402 2.6 version to the 3.x version without any hitches?
[LG Optimus 2x] kickokim:
It is a system rw issue, there is a fix on older post. You have to back up, wipe system parition and restore. There is a zip that does all that, look for it in post from about a week ago!

Ps. It's a good idea to put this in op since so many people still have system rw issue.
[LG Optimus 2x] powwow88:
Ye, I think that too.
[LG Optimus 2x] BiugEE:
Same here. Stay by "Extract Files".

This help me every time:

1. Pull Battery

2. Put in Battery and boot (wait wait wait)

3. Flash again and now it´s work without hanging by "Extract Files"

I have the same Error with the last 4 (maybe 3 or 5) versions from the kernel.
[LG Optimus 2x] kickokim:
This zip does all that in one flash, maybe this should go in op untill issue is solved.

Flashed version from 12041812## I assume it didn't work at all.

I flashed original CM7, boot to system and wipe PimpMyCpu configuration. Flashed version 12041812##, boot to system, start PimpMyCpu configuration and in default stock profile see total mess of values for under-volt - about -1342457613mV. So this seems very very weird..

I correct these values, create profiles. Device went to sleep and never wake up, boot stops on second LG logo.

I have to go back to version 12040211##.
[LG Optimus 2x] vadonka:
Im reuploaded today version, compiled with gcc 4.5.4 and without using ccache. its the slowest method for the compiling but its the safest and the most stable.

because the latest changes doesn't cause boot issues it must be the compiler. im updated the gcc 4.7.1 today just before im build the kernel, so it maybe the linaro source have a commit what is cause issues.

so try this reuploaded version.

i guess the gcc 4.7.1 doesn't stable :(
[LG Optimus 2x] powwow88:
It's working now.:)
[LG Optimus 2x] vadonka:
Great! im happy :)
[LG Optimus 2x] powwow88:
Maybe we were happy a bit too early.:( I flashed it and booted up left phone on charger. I checked back a little later and pushed turn on to unlock and nothing happend. I pulled out battery turn on then cm7 logo froze after a short time. Battery out wipe cache dalvik reflash kernel and now it's stuck at 2nd LG logo again.

[LG Optimus 2x] hadi_rena:
@vadonka: could you put these on the OP ? There is still a lot of user have system r/w problem (including me after upgrade to build #91) and I use this fix is 100% worked for me and other people.
[LG Optimus 2x] morckx:
Strange, I have no problems with 1204230922-ETaNa_OC_OTF-3.0 (compiled with gcc 4.7) @ 1.4 GHz.

Anyway, I mentioned my posts mainly because before reporting errors here, we should probably all make sure that the system fs, but also data and cache fs do not contain errors. Otherwise strange things that are not (directly) related to the kernel do happen and vadonka's great efforts to solve them might go into wrong directions and will eventually be in vain :)
[LG Optimus 2x] hadi_rena:
Could you provide us how to check system fs, cache, data partition ? So we can check before report an error. It would be awesome if you also provide how to repair it.

For system fs I think we can use some command from old post to get system features which vadonka told us. I notice there is need_recovery and after I use fix then r/w problem fixed and there is no need_recovery again in system features

Will monitor battery life.

EDIT 15:49

Okay, not so nice now. Series of random reboots (during dialling), and after one of them the phone reported an "unknown baseband." Some BSOD, too, during charging and also at one attempted reboot.

3)pulled off battery and reflashed temasek rom: sucess

After that seems everything ok, but i lost my google account (contacts etc )and i cant add it again, there is nt an option for google accoun (only skype and exhange )

mine here already format /system format data/factory reset. still stuck on LG logo using your newly upload kernel :(
[LG Optimus 2x] morckx:
To check them (in the order system, cache, data) in read-only modus (your fs will not be modified), enter the following in CWM recovery via adb shell:

e2fsck -fnC0 /dev/block/mmcblk0p1
e2fsck -fnC0 /dev/block/mmcblk0p2
e2fsck -fnC0 /dev/block/mmcblk0p8

If there are errors you can try to let them repair automatically using the options "-fpC0" and if that does not work "-fyC0" (but I guess "p" or "y" makes no difference). The repair may, however, have changed files so that boot failures or SODs are to be expected. In that case only formatting and re-installing helps.

BTW: Repairing only works when the file system is not mounted. So you might e.g. have to enter "umount /cache".

"needs_recovery" as output of "tune2fs -l <fs>" is not a very good indicator because the flag is always set once somethings is written on the fs and only removed when the fs is unmounted. This is to make sure that the flag is set whenever a fs is not properly unmounted.

---------- Post added at 04:27 PM ---------- Previous post was at 04:22 PM ----------

The easiest explanation would be that you don't have the gapps installed (or they are broken).
[LG Optimus 2x] TrymHansen:
Vadonka, as you know I've made this app to adjust some OTF parameters on OTF-compatible kernels like ETaNa.

In theory it should work seamlessly together with the Etana twaker app, my app only modifies some lines in in tweakaio.conf. It seems, however, as if the ETaNa tweaker app only reads the file in onCreate, and then writes any changes from a local copy.

What happens is ofcourse that if my app makes any changes, and the user goes back to the Etana-tweaker, it will not pick up on the new values.

So I want to politely request that you modify the app to read the tweakaio.conf file in onResume() instead of in onCreate(), so that our apps can peacefully co-exist.
[LG Optimus 2x] buluba89:
Thanks for the quick response.

I thought that maybe something happened to gapps so i reflashed gapps. Nothing happened... google store is opening but asks for google account, if i click add it just close

Edit

I did what morckx said at previous page: wipe system, reflash everything and re init.

Everything works now :D

Thanks a lot!
